EJPECIFICATION forming part of Letters Patent No. 537,39 4, dated April 9, 1895.

Application filed April 23, 1894. Serial No. 508,749. (No model.)

Be it known that 1, Louis STRIOKEL, a citizen of the United States, residing at Detroit, county of WVayne, State of Michigan, have in vented a certain new and useful Improvement in Brush-Making Machines; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had t the accompanying drawings, which form a part of this specification.

My invention has for its object an improved machine for the manufacture of brushes, whereby their manufacture may be ec0nomized and simplified, the machine being intended to save labor and to accomplish th desired ends in a superior manner.

My improved machine is calculated and designed to force the stock into the brush head,

to secure the stock in the head by suitable binders, to drive the nails required to hold the binders in place, to drive the ends of the hind ers into the brush head, to automatically form as well as to drive the nails, and also to automatically form and drive the staples into the ends of the brush head to secure the ends of the stock in place.

My invention, therefore, consists in the general construction, combination and arrangement of the devices and appliances hereinafter specified and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation illustrating my invention. Fig. 2 is a plan view. Fig. 3 is a front elevation. Fig. 4 is a detail View in frontelevation showing features of the nail cutting and driving mechanism. Fig. 5-is a vertical section on the line 5-5, Fig. 4. Fig. 6 is alongitudinal vertical section on the line 6--6, Fig. 2, showing the machine in its inoperative or retracted condition. Fig. 7 is a detail view of one of the pitman connections operating the staple mechanism. Fig. 8 is a vertical longitudinal section showing the parts of the machinein advanced or operative position. Fig. 9 is a detail view of one of the staple driver oars. Fig. 10 is a detail view in plan of the staple making and driving mechanism. Fig. 11 is a vertical section on the line 1l-ll, Fig. 10.

Fig. 15 is a view in perspective illustrating features of the wire feeding and nail driving mechanism. tail end View of the tilting bar beneath the wire feeders. Fig.1? is a rearelevation of the nail cutter andrdriver, shown in Fig. 4. Fig. 18 is a front elevation of the staple maker shown in plan in Fig. 10. Fig. 19 is a detail view of a brush made by my improved ma chine, the view of the brush being shown to more clearly illustrate what my improved machine is designed to accomplish.

To more fully explain the purpose of my machine, the numeral 1 indicates a brush head formed with longitudinal grooves 52, into which the stock 3 is forced in any suitable manner. A longitudinally extended binder wire 4 is forced with the stock into the corresponding groove 2, the ends of the binder wire being bent, and, in the completed brush, driven into the ends of the brush head as indicated at 5. Staples 6 are driven over the ends of the stock into the ends of the brush head to hold the stock in place, and nails 7 are driven over the binder wire into the brush head to effectually secure the binder and stock in place. To secure these results, my machine includes any suitable supporting frame A provided with a table A upon which the brush head is engaged in advance of the nail driver block B, and against which the head is firmly held by a movable head block C. The head block is conveniently operated by means of a lever O fulcrumed to the table A, as shown at c, the lever Obeing operated by a tread1eO The upper end of the lever G is preferably forked, as shown at c and o adjusting screws 0 and C connecting the head block G with the extremities of the forks c and c Fig. 16 isa de- It will be evident that by placing the foot vertically movable uprights D made reciprocatory in suitable ways (1, indicated in dotted lines, Fig. 3, in the supporting frame.

D denotes a cross-bar located between the uprights D and made vertically adjustable, as by adjusting screws D connecting the extremities of the cross-bar with the upper inwardly directed extremities d of the uprights D. Upon this cross-bar .D is engaged the customary driving plate E by which the stock and the binder wire are forced into the brush head. To this end, the cross-bar may be provided with a supporting head 1) provided with a supporting pin d, the driving plate being constructed with an orifice to receive said pin. The descent of the vertical carriage D presses the stock into the brush head, and remains in such position, to hold the stock and the binder wire in place until the nails are driven over the binder wires to secure them in place.

F is the main driving shaft suitably j0ur naled in the supporting frame A. While I do not limit myself to any particular driving mechanism, I have shown the driving shaft provided with a driving pulley F.

G is a rotatable shaft journaled in the supporting frame A, provided with a gear G meshing with a pinion F of the driving shaft F.

F denotes a clutch of any suitable construction adapted to engage the pulley F. As shown, the clutch is provided with alever arm F connected by a pitman F with a treadle F.

F is a retracting spring.

H denotes a horizontally reeiprocatory carriage which may be formed with side bars H, a front cross head H and a rear crossbar-H H denotes oscillatory uprights connected respectively by connecting bars H with crossbars 11 0f the carriage H. The shaft G is provided with a cam G provided with rollers g extended therefrom on either side, and arranged to bear upon the uprights H at a given stage in the operation of the apparatus, to press said uprights forward and thereby advance the carriage H. The lower extremities of the vertical side-bars D of the carriage D are connected by a cross bar D WVith this cross bar D is connected a rearwardly extended lever I fulcrumed toward its forward end, as at I, the rear end of said lever resting upon the periphery of the cam G Therear extremity of the lever I is weighted, as shown at 1 to hold the carriage D normally in a raised position. As the cam rotates, the rear extremity of the lever I will be lifted, thereby forcing downward the carriage D. In this manner, both the vertical carriage D and the horizontal carriage H are operated by the cam G H denotes retracting springs to retract the carriage H. The cross head H is provided with nail driving arms or fingers H Supported upon the side-bars H of the carriage H, as upon brackets h, is a feeder bar H provided with a suitable number of feeders I h, the bar H being rotatable in the brackets h.

H is a guide plate through which the wire is led to form the staples and the nails, the wires 71, being the wires from which the nails are made, and the wires It being the wires from which the staples are made. To advance the wire to the staple making and nail making mechanism, the feeders h are arranged to grip the wire at the proper time when the carriage is advanced, and thereby advance the wire from the reels J. The shaft H being rotatable evidently permits the feeders to slide over the wire when the carriage H is retracted. The feeders h are constructed with an edge at their lower ends to suitably grip the wire when in contact therewith as the carriage H is advancing.

The drivers H are made reciprocatory in suitable orifices b in the nail driver block B located in advance of the cross head H The nail driver block B is also provided with suitable orifices I) through which the wire is fed.

B denotes a suitable cutting blade made vertically reciprocatory within a suitable channel b in the driver block B.

B denotes a clamping plate made adjustable for holding the knife in position in said channel. Any desired adjustment of the plate B may readily be effected by set screws b entering the front face of the driver block B. Instead of making the driver block B of an integral body,I prefer to construct it with an upper channeled block B engaged therewith, as by bolt b. The plate B and block B are formed with a series of elongated chambers if, of a length suitable for a single nail. In the operation of cutting the nails, the wire it is advanced through the orifices b beneath the elevated cutter blade B, to the forward end of the corresponding chamber The knife descending, cuts the wire, the nails dropping to the base of the chambers b in advance of the drivers H When said drivers are advanced in the orifices b, the nails are driven therebyforward through the channels b into the head block. To operate the knife B, the knife is provided with a lever arm 13, fnlcrumed upon a suitable standard B engaged upon the driver block B, as shown at U The carriage D is provided with a rearwardly extended arm d arranged to strike the outer end of the lever arm B as the carriage D descends, thereby lifting the cutter. The cutter descends when the lever B is released from engagement with the arm d and cuts the wire to make the nails. This opera tion of the cutter and the formation of the nails take place in advance of the forward movement of the carriage H, thus forming the nails in readiness for the forward movement of the drivers H It is evident that the carriage H must advance and retract a suitable distance to drive the nails into the brush head and to withdraw the drivers H out of the way of the nail cut- IIO IIS

ter,while the wires it must only be advanced the length of a single nail. Therefore, the carriage H must be advanced and retracted a considerable distance more than it is required to advance the wire at each operation. In consequence, the feeders It must be arranged so as not to grip the wire until the carriage H' has been suitably advanced, or advanced a considerable distance of its forward movement. To accomplish this result, I locate beneath the feeders a tilting bar K, eccentrically journaled in the brackets h, as shown at is, one of the eccentric journals being shown at Fig. 16. Depending from the tilting bar K is a tilting arm K. To tilt said bar K, I locate'a forked bar K which is made adjustable in a suitable bracket Win the frame A as byan adjusting nutk The tilting bar K is preferably rounded at its front upper corner, as shown at It. In its normal position the bar K lifts the feeders it off the corresponding wires so that the carriage Hmay be advanced while the feeders are so lifted, without advancing the wire. At a suitable stage, however, in the advancement of the carriage H, the tilting arm K strikes the forked bar K in consequence of which, the bar K is tilted, and owing to'its being eccentrically journaled permits the feeders h to drop upon and grip the wires which are consequently advanced the remainder of the distance, through which the carriage H is moved forward. WVhen the carriage is retracted, the bar K resumes-its normal condition, lifting thetfeeders. In this manner as the carriage H is advanced, the nails are cut and driven. As the pulleys g and the cam G ride out of engagement with the oscillatory bars H, the carriage H is automatically retracted by means of the springs H ready for another advance movement.

I will now proceed to describe the staple making and driving mechanism.

Inasmuch as the staple making mechanism is duplicated on each side of the machine, it will only be necessary to describe the construction of one of them. Accordingly, L represents a staple block secured upon the bed or table A of the supporting frame in any suitable manner; This block is constructed with a laterally extended groove L in which is reciprocated a staple driver M. Above the driver M is located a staple making die plate N, formed with a suitable die n at its forward end. I prefer to form the groove L in a piece of steel L Fig. 18, set into the block L, inasmuch as said groove forms a guide for the reciprocation of the driver M. The driver is preferably formed towards its forward end with lateral flanges, as shown at m to engage the staple, the groove being of similar form in cross section, as indicated in Fig. 18. The block L is provided with a top plate L secured thereupon, formed with a socket L to receive the end of the customary brush clamp, not shown. The wire from which the staples are made is fed through a suitable orifice, as at Z, transversely to the movement of the driver M. The plate L is constructed with an outwardly projecting die Z of suitable form to permit the die plate N advancing thereabout to bend the staple, the staple falling when completed into the upper portion of the groove L, in position to be driven by the advancement of the driver M into the end of the brush head. Beneath the socket L is agroove L shown most clearly in Figs. 10,11, and 18, essentially of the same width as the base or body of the driver M, the groove L serving to receive the hook end of the binder wire 5, shown in Fig. 19, located over the stock to retain the same in place. As the driver M advances, it both drives the staple and clinches the binder wire into the head of the brush in one operation.

To reciprocate the die plate N, I provide a bell crank lever P fulcrumed, as at P, upon the block L, the front end of said leverP engaging a stud N upon the die plate N. With the opposite end of the lever P is engaged a pitman Q, the forward portion of the pitman being provided with an elongated .slot q engaging-a spur or stud P on the lever P. Upon the shaft G are located cams G and G4 to reciprocate the duplicate pitmen Q Q. With the rear ends of the pitmenQ Q are engaged vertical oscillatory levers R and R, fulcrumed at their base, as shown at B Fig. 1, the cams G3 and G bearing upon said levers R and B respectively to force them forward, said pitmen being retracted by springs R and R As the levers R and Rare thrown forward, the corresponding bell crank levers P are operated to advance the die plateN connected therewith.

I prefer to construct each pitman Q in two parts, as indicated more specifically in Fig.

a 7, to permit of the regulation or adjustment of the pitman as may be required. This may be accomplished by providing each part Q, Q with adjacent brackets q and g an adjusting screw Q being provided,whereby said brackets may be set at any given distance the one from the other, to lengthen or shorten the entire pitman Q. The arm or part Q is shown underlapping the part Q. When the two parts have been properly adjusted, they may be united by suitable bolts g To advance the driver M, I provide a horizontally oscillatory lever M havingajointed engagement with the corresponding driver, as shown at m. The rear extremity of the lever M is beveled, as shown at m Upon each of the side bars H of the carriage H, is engaged a cam S, against the front face of which bears the beveled rear face or end of the corresponding lever M. It will readily be seen that as the carriage H advances, the levers M and M of the duplicate staple making mechanism, are spread apart at their rear ends, throwing their forward ends inward to advance the corresponding driver M, each leverM being fulcrumed intermediate its ends, as shown at m A spring M connecting the rear extremities of the two levers M, M, re' tract the corresponding drivers when the carriage H retracts.

The parts of the machine are so adjusted as to co-act in suitable succession. Thus, the staple making mechanism is first operated to form the staples. This is accomplished by the arrangement of the cams G and G to operate in advance of other parts of the machine, or in advance of the operation of the cam G After the two cams G G have operated the mechanism to make the staples, the cam G operates to force downward the vertical carriage D, and then rollers g are brought into contact with the vertical levers H H to force forward the carriage which operates the nail making and driving mechanism.

The several parts may be retracted in any suitable manner within the scope of my invention.

The feeders 7t are made laterally adjustable on the shaft 11 for different sizes of brushes. The two bell crank levers P of the duplicate staple making mechanism are turned in opposite directions upon the two sides of the machine, that shown in Fig. 10 being at the left hand of the machine.

The head-block H is cut away on its upper face as shown in Fig. 15, at V, to allow the carriage to feed the staple wire farther than the nail wire. It will be observed by reference to said figure that the orifices 0, through which the wires h are fed are lower than the orifices 12' through which the wires 77, are fed. This construction permits the corresponding feeders to grip the staple wires more quickly than the intermediate feeders grip the nail wires. The staple wire feeders, it will be observed, are a little longer than the nail wire feeders. The staple wire is cut for the staples on the edges of the dies.

The hook Z shown in Fig. 11 attached to the wall of the socket L is to prevent the die plate I from withdrawing the staple in case it might be clamped or otherwise held fast in the orifice n of the staple plate N in its retreat.

The mode of making the brush is as follows: The head of the brush is held in place between the nail driver block and the head block 0. The stock and binder wire for a single groove are then forced into the brush head by means of the descent of the carriage D and driving plate E. The nails are then driven over the binder wires and also the staples into the ends of the brush head by the mechanism hereinbefore described. The hook projects downward behind the staple and strips it from the die when the die is retracted.
